### Run Piflow Server：

- `run piflow server on Intellij`:   
  - download piflow: git clone https://github.com/cas-bigdatalab/piflow.git
  - import piflow into Intellij
  - edit config.properties file
  - build piflow to generate piflow jar:   
    - Edit Configurations --> Add New Configuration --> Maven  
    - Name: package
    - Command line: clean package -Dmaven.test.skip=true -X  
    - run 'package' (piflow jar file will be built in ../piflow/piflow-server/target/piflow-server-0.9.jar)  
    
  - run HttpService:   
    - Edit Configurations --> Add New Configuration --> Application  
    - Name: HttpService
    - Main class : cn.piflow.api.Main  
    - Environment Variable: SPARK_HOME=/opt/spark-2.2.0-bin-hadoop2.6(change the path to your spark home)  
    - run 'HttpService'
  
  - test HttpService:   
    - run /../piflow/piflow-server/src/main/scala/cn/piflow/api/HTTPClientStartMockDataFlow.scala
    - change the piflow server ip and port to your configure
  
  
- `run piflow server by release version`:
  - download piflow.tar.gz:   
    https://github.com/cas-bigdatalab/piflow/releases/download/v1.1/piflow-server-v1.1.tar.gz  
    
  - unzip piflow.tar.gz:  
    tar -zxvf piflow.tar.gz
    
  - edit config.properties  
  
  - run start.sh、stop.sh、 restart.sh、 status.sh  
  
  - test piflow server
    - set PIFLOW_HOME  
      - vim /etc/profile  
        export PIFLOW_HOME=/yourPiflowPath/bin  
      	export PATH=$PATH:$PIFLOW_HOME/bin  
      - command   
        piflow flow start example/mockDataFlow.json  
        piflow flow stop appID  
        piflow flow info appID  
        piflow flow log appID  
      
        piflow flowGroup start example/mockDataGroup.json  
        piflow flowGroup stop groupId  
        piflow flowGroup info groupId  
        
- `how to configure config.properties`
     
      #spark and yarn config
      spark.master=yarn
      spark.deploy.mode=cluster
      
      #hdfs default file system
      fs.defaultFS=hdfs://10.0.86.191:9000
      
      #yarn resourcemanager.hostname
      yarn.resourcemanager.hostname=10.0.86.191
      
      #if you want to use hive, set hive metastore uris
      #hive.metastore.uris=thrift://10.0.88.71:9083
      
      #show data in log, set 0 if you do not want to show data in logs
      data.show=10
      
      #server port
      server.port=8002
      
      #h2db port
      h2.port=50002

### Run Piflow Web：
  - Visit address, download the corresponding *.tar.gz file, and modify the corresponding configuration file（`The version must be consistent with piflow-server`） 
    - https://github.com/cas-bigdatalab/piflow-web/releases/tag/v1.1  
  
### Restful API：
